Description

Technical Field

[0001] This utility model relates to the field of galvanizing equipment technology, and more specifically, to a galvanizing pool for the production of galvanized steel strip. Background Technology

[0002] A galvanizing bath is a container used in the galvanizing process to hold galvanizing solutions (such as molten zinc in hot-dip galvanizing and electroplating solutions in electroplating). It is a key facility for galvanizing the surface of metal products such as steel strips. Its core purpose is to form a zinc layer on the surface of metal products through a specific process, thereby improving the corrosion resistance, wear resistance and appearance quality of the metal products.

[0003] The production of galvanized steel strip requires an outer galvanizing process in a galvanizing bath. Existing galvanizing methods typically involve using guide rollers to transfer the steel strip into the molten zinc bath, where galvanizing is performed via electroplating or melting, and then the strip is guided out by the guide rollers. However, during this process, external factors and contact with the guide rollers can affect the thickness of the galvanized film, leading to uneven coating and impacting the quality of the product in subsequent use. Therefore, we propose a galvanizing bath for the production of galvanized steel strip. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a galvanizing tank for the production of galvanized steel strip, so as to solve the technical problem that the thickness of the galvanized film on the surface of the steel strip is uneven and affects the quality of the finished product.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a galvanizing tank for producing galvanized steel strip, comprising a coating mechanism, an internal box, and an adjusting plate. The internal box is installed in the middle of the tank body. Both ends of the material inlet on both sides of the tank body are provided with retractable pressure rods. Embedded boxes are embedded in both ends of the internal box. Guide rollers are rotatably installed on both sides of the upper opening of the internal box. Side openings are opened on both sides of the upper end of the internal box. The coating mechanism is installed between the side openings of the internal box. The coating mechanism consists of four support rollers, and the four support rollers are arrayed on both sides of the internal box. The support rollers are connected by a transmission belt. The outer ends of the support rollers are connected to the inside of the tank body through an adjusting mechanism. The outer ends of the two support rollers of the side cylinder are connected by a retainer.

[0006] This utility model is powered by an external power supply. The operator starts the device through an external control device, guiding the steel strip through the notch at one end of the device, so that the steel strip fits against the lower side of the telescopic pressure bar. Then, the steel strip passes over the upper side of the guide roller and through the lower side of the transmission belt. The cylinder that makes up the adjustment mechanism is activated, driving the drive box to rise and fall. The drive box synchronously drives the coating mechanism to rise and fall. The inner side of the transmission belt of the coating mechanism is equipped with a brush, which fits against the surface of the steel strip. Through the heating component and pump structure embedded in the box, the zinc plating liquid in the tank is poured into the built-in box and heated. The continuous filling and introduction makes the level of the zinc plating liquid in the built-in box level with the overflow port. The zinc plating liquid flows back into the tank from the overflow port. The continuous flow of the zinc plating liquid in the built-in box prevents impurities on the liquid surface from affecting the zinc plating process. The system works by starting the motor inside the drive box, which drives the main sprocket to rotate. The main sprocket, through chain transmission, synchronously drives the support roller at the end of the auxiliary sprocket to rotate. The rotation of the support roller drives the transmission belt, which has a trapezoidal structure. Its lower side is located inside the overflow port. When the galvanizing liquid overflows from the inner box, it passes through the overflow port, immersing the inner bristles of the rubber strip on the lower side of the transmission belt in the galvanizing liquid. Then, through transmission, the rubber strip scrapes against the side of the steel belt, causing the rubber strip to unfold. The inner bristles of the rubber strip apply the galvanizing liquid to the surface of the steel belt, thickening the galvanized film on the steel belt surface and ensuring the quality of the steel belt. The trapezoidal distribution structure of the transmission belt facilitates immersion in the galvanizing liquid for loading, and the coating can be completed during transmission, making it highly practical.

[0007] Preferably, the adjustment plate is slidably installed inside the side opening of the built-in box, and both ends of the side opening are provided with spring-loaded components, which are composed of a telescopic rod and a spring, and the upper end of the spring-loaded components is connected to the adjustment plate.

[0008] Preferably, an overflow port is provided at the middle of the upper end of the adjusting plate, and the lower end face of the transmission belt is located inside the overflow port.

[0009] Preferably, a side box is installed on the outside of the cage, and a main sprocket is rotatably installed inside the side box. An auxiliary sprocket is provided at one end of the support roller connected to the cage, and the auxiliary sprocket of the same side support roller is connected to the main sprocket by chain drive.

[0010] Preferably, the adjustment mechanism consists of a limiting frame and a cylinder, with the cylinder installed on the side of the limiting frame and a drive box installed on the upper end of the cylinder. The output shaft of the motor in the drive box is connected to the shaft of the main sprocket, and the retainer is installed inside the limiting frame.

[0011] Preferably, the adjusting slot of the limiting frame has a recess inside, and the recess is adapted to the chain of the transmission connection between the auxiliary sprocket and the main sprocket.

[0012] Preferably, rubber sheets are evenly distributed on the outer side of the transmission belt, the rubber sheets are inclined, and the inner side of the rubber sheets is provided with bristles.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the design of an internal box, guides the steel strip through a notch at one end of the device, allowing the steel strip to adhere to the lower side of the telescopic pressure rod. Then, the steel strip passes over the upper side of the guide roller and through the lower side of the transmission belt. Activating the cylinder that forms the adjustment mechanism drives the drive box to rise and fall. The drive box synchronously drives the coating mechanism to rise and fall. The inner side of the transmission belt of the coating mechanism is equipped with a brush that adheres to the surface of the steel strip. Through the embedded heating components and pump structure, the zinc plating liquid in the pool is poured into the internal box and heated. Continuous filling and introduction ensure that the level of the zinc plating liquid in the internal box is level with the overflow port. The zinc plating liquid flows back to the pool from the overflow port. This continuous flow ensures that the zinc plating liquid in the internal box continues to flow, preventing impurities on the liquid surface from affecting the zinc plating effect.

[0015] 2. This utility model also incorporates a coating mechanism. The motor inside the drive box drives the main sprocket to rotate. The main sprocket, via chain transmission, synchronously drives the support roller at the end of the auxiliary sprocket to rotate. The rotation of the support roller drives the transmission belt, which has a trapezoidal structure. Its lower side is located inside the overflow port. When the galvanizing liquid overflows from the inner box, it passes through the overflow port, immersing the rubber sheet on the lower side of the transmission belt in the galvanizing liquid. The inner bristles of the rubber sheet absorb the galvanizing liquid, and the transmission belt adheres to the surface of the steel belt. During transmission, the rubber sheet is scraped up by the side of the steel belt, causing the brush surface to unfold and adhere to the surface of the steel belt. Then, through transmission, the zinc liquid on the brush bristles is applied to the surface of the steel belt, thickening the galvanized film on the steel belt surface and ensuring the quality of the steel belt. The trapezoidal distribution structure of the transmission belt makes it easy for the brush bristles to be immersed in the galvanized liquid to complete the material application. At the same time, the material application can be completed during transmission, making it highly practical. The scraping action unfolds the inward-curving rubber sheet, making it easier for the inner brush bristles to adhere to the steel belt and ensuring the coating quality. Attached Figure Description

[0025] like Figures 1 to 5 As shown, this utility model relates to a galvanizing tank for producing galvanized steel strip, including a coating mechanism 2, an internal box 3, and an adjusting plate 5. The internal box 3 is installed in the middle of the tank body 1. Both ends of the material inlet on the upper side of both ends of the tank body 1 are provided with retractable pressure rods 101. The internal boxes 3 are embedded in both ends of the internal box 3. Guide rollers 301 are rotatably installed on both sides of the upper opening of the internal box 3.

The adjusting plate 5 is slidably installed inside the side openings 303 of the internal box 3. Both ends of the side openings 303 are provided with spring-loaded components 304. The spring-loaded components 304 are composed of telescopic rods and springs, and the upper end of the spring-loaded components 304 is connected to the adjusting plate 5. The spring-loaded components 304 drive the adjusting plate 5 to raise and lower its height, which is convenient for adapting to the overflow of galvanizing liquid. The upper middle of the adjusting plate 5 is opened. An overflow port 501 is provided, and the lower end face of the transmission belt 202 is located inside the overflow port 501. A brush is provided on the inner side of the transmission belt 202. The steel belt is guided from the notch at one end of the device, so that the steel belt fits against the lower side of the telescopic pressure bar 101. Then the steel belt passes over the upper side of the guide roller 301 and passes through the lower side of the transmission belt 202. The cylinder that makes up the adjustment mechanism 4 is activated to drive the drive box 401 to rise and fall. The drive box 401 drives the coating mechanism 2 to rise and fall simultaneously. A brush is provided on the inner side of the transmission belt 202 of the coating mechanism 2. The brush fits against the surface of the steel belt. Through the heating component and pump structure embedded in the box 302, the zinc plating liquid in the pool 1 is poured into the built-in box 3 and heated. The continuous filling and introduction make the level of the zinc plating liquid in the built-in box 3 level with the overflow port 501. The zinc plating liquid flows back from the overflow port 501 to the pool 1. The continuous flow keeps the zinc plating liquid in the built-in box 3 flowing, avoiding the residual impurities on the liquid surface from affecting the zinc plating effect.

[0026] like Figures 2 to 8As shown, this utility model relates to a galvanizing tank for producing galvanized steel strip, including a coating mechanism 2, an inner box 3, and an adjusting plate 5. The coating mechanism 2 consists of four support rollers 201, which are arrayed on both sides of the inner box 3. The support rollers 201 are connected by a transmission belt 202. The outer ends of the support rollers 201 are connected to the inside of the tank body 1 through an adjusting mechanism 4. The outer ends of the two support rollers 201 on the side cylinder are connected by a retainer 203. A side box 206 is installed on the outside of the retainer 203, and a main sprocket 205 is rotatably installed inside the side box 206. Auxiliary sprockets 204 are arranged in a circular array at one end of the support roller 201 connected to the retainer 203. The auxiliary sprockets 204 on the same side of the support roller 201 are connected to the main sprocket 205 via chain drive. The adjustment mechanism 4 consists of a limit frame 402 and a cylinder. The cylinder is installed on the side of the limit frame 402, and a drive box 401 is installed on the upper end of the cylinder. The output shaft of the motor inside the drive box 401 is connected to the shaft of the main sprocket 205. The retainer 203 is installed inside the limit frame 402. The adjustment slot of the limit frame 402 has a recess, and the recess is connected to the transmission-connected auxiliary sprocket 205. 4. The chain of the main sprocket 205 is compatible with the transmission belt 202. Rubber sheets 207 are evenly distributed on the outer side of the transmission belt 202. The rubber sheets 207 are inclined and have bristles on the inner side. The motor in the drive box 401 drives the main sprocket 205 to rotate. The main sprocket 205 drives the support roller 201 at the end of the auxiliary sprocket 204 to rotate synchronously through the chain drive. The rotation of the support roller 201 drives the transmission belt 202 to move. The transmission belt 202 is trapezoidal in structure and its lower side is located inside the overflow port 501. When the zinc plating liquid overflows from the built-in box 3 to the outside... When the overflow port 501 is reached, the lower side of the transmission belt 202 is immersed in the galvanizing solution. The bristles on the inner side of the rubber sheet 207 on the lower side of the transmission belt 202 absorb the galvanizing solution. During the transmission of the transmission belt 202, the side of the steel belt scrapes against the rubber sheet 207 to spread it out. The bristles on the inner side of the rubber sheet 207 apply the galvanizing solution to the surface of the steel belt, thickening the galvanized film on the surface of the steel belt and ensuring the quality of the steel belt. The trapezoidal distribution structure of the transmission belt 202 makes it easy to be immersed in the galvanizing solution to complete the loading. At the same time, the loading can be completed during transmission, which is highly practical.

[0027] Working Principle: This embodiment provides a galvanizing tank for producing galvanized steel strip. In use, the steel strip is introduced through a notch at one end of the device, allowing it to adhere to the lower side of the telescopic pressure bar 101. The steel strip then passes over the upper side of the guide roller 301 and through the lower side of the transmission belt 202. The cylinder forming the adjustment mechanism 4 is activated, driving the drive box 401 to rise and fall. The drive box 401 simultaneously drives the coating mechanism 2 to rise and fall. A brush is provided inside the transmission belt 202 of the coating mechanism 2, adhering to the surface of the steel strip. Through the heating components and pump structure embedded in the box 302, the galvanizing liquid in the tank 1 is poured into the built-in box 3 and heated. Continuous filling and introduction ensures that the level of the galvanizing liquid in the built-in box 3 is flush with the overflow port 501. The galvanizing liquid flows back from the overflow port 501 to the tank 1. This continuous flow keeps the galvanizing liquid in the built-in box 3 continuously... To prevent impurities from remaining on the liquid surface from affecting the galvanizing effect, the motor inside the drive box 401 drives the main sprocket 205 to rotate. The main sprocket 205 drives the support roller 201 at the end of the auxiliary sprocket 204 to rotate synchronously through the chain drive. The rotation of the support roller 201 drives the transmission belt 202 to move. The transmission belt 202 has a trapezoidal structure and its lower side is located inside the overflow port 501. When the galvanizing liquid overflows from the built-in box 3, it passes through the overflow port 501, causing the brush bristles inside the rubber sheet 207 on the lower side of the transmission belt 202 to be immersed in the galvanizing liquid. When the transmission is carried out, the side of the steel belt scrapes and causes the rubber sheet 207 to be lifted, so that the brush bristles on its inner side adhere to the surface of the steel belt. Then, through the transmission, the galvanizing liquid inside the brush bristles is brushed onto the surface of the steel belt, thickening the galvanized film on the surface of the steel belt and ensuring the quality of the steel belt.
